It hits every ''racy'' teentertainment mark so hard (everyone's hair is so full - of secrets!) that it feels like the only thing missing is a visit from the ghosts of Jennifer Love Hewitt and Freddie Prinze Jr.

While no one beyond the show's target audience--teens in need of something to squeal over until Gossip Girl returns next season--would claim that Pretty Little Liars has a voluminous body, I must concede that it has a lustrous shine.

Sure, there's a lot here that sustains more eye-rolling than interested stares, but a little patience might be warranted. Only with future episodes can Liars prove whether it's "Desperate Housewives" for tweens or just another trashy, pretty little error.

Pretty Little Liars doesn't have the sense of humor -- or the wardrobe -- of "Gossip Girl." In fact, a surprising number of scenes call for bikinis. But the ongoing mystery (not to mention a secret referred only to "the Jenna thing") may prove irresistible to young people.

The mystery makes Pretty Little Liars more entertaining than the tedium of Gossip Girls, and many parents might actually enjoy watching along with their young adults, who can explain why this sort of thing is so alluring to them.

The ridiculously expensive wardrobes, the fabulous hair and makeup, plus a high school with not a single fatty is well, yes, the stuff of teen fantasy. And that is exactly what Pretty Little Liars is: a glamorous, spooky, adolescent fantasy.
